I am a brand new Treg owner - just bought a 2012 V6 Lux. I test drove the vehicle 3x prior to purchasing but never turned the engine off because the sales consultant was required to drive it back into the gated lot each time. I drove the Treg home and notice a grinding noise when I turned the engine off. Sounds perfect when I turn it on - no issues there. It only lasts about a second but it just doesn't sound right. Anyone else ever experience this? This is my first VW so not sure if this is normal or not. I plan to take it to the dealer next week to check it out. I am still under warranty for about 2.5 more weeks. Thanks in advance!!
